<p><b>Abstract</b>—We respond to criticism by D. Berry and W. Tichy of our paper that appeared in the March 2002 issue of <it>IEEE Transactions on Software Engineering</it>. Many of the supposed faults they identify in our experiment are a result of a misunderstanding on their part, while others are inherent aspects of an educational experiment. We present counterarguments that explain why our experiment is valid.</p>
